TENTER CLIP.

Alipiication med January 19, 192s. serial No. 247,786.

This invention relates to an improved construction of tenter clip andhas for its object to provide a clip of this character which is adaptedfor engaging open mesh fabric,

more particularly Wire fabric, the clip having means for entering themeshes of the fabric to hold its edge against tension.

A further object of the invention is the provision of a clip of thischaracter having a guide portion for the support of the margin of thefabric and having a blade or member with an edge portion arranged toride on the selvage of the fabric as the selvage is being drawnoutwardly Jcoward the mouth of the clip, the blade being also providedWith a hook or engaging end portion shaped to enter Athe meshes of thefabric to retain the fabric in the clip, whenA under tension.

A still further object of the invention is the provision of a cliphaving a plurality of independently movablemembers arranged to separablyenter. the meshes of the fabric to retain the same, whereby if one ormore of the engaging members should for any cause fail to enter themeshes of the fabric such action would not prevent the others of theengaging members of the set from functioning.

With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described, andparticularly pointed out in the appended claims.

In the accompanying drawings: v

Figure ly is a top view illustrating my 1mproved tentering clip andshowing in dotted lines a section of open mesh fabric such as wirefabric as engaged by the clip. y

Figure 2 is "a perspective view of one of the mesh fabric engagingmembers or blades.

Figure 3 shows the body of the clip with a slotted guide for the fabricand a plurality Vof spaced openings in which the mesh engaging membersare to be mounted.

Figure 4 is a side elevation illustrating one of the mesh engagingmembers as having a portion Vriding upon therselvage of the fabric andbeing held outof engaging Vposition thereby. Y l v Y Figure 5 shows theselvage as having been withdrawn from beneath the guiding portion 'ofthe engagingmember and permitting the member to dropand cause its hookportion ,plished tion l1.

to engage the mesh and engage `the selvage of the fabric.

Figure 6 is a section on line 6 6 of Figure 5 showing the plurality ofengaging members as hooked over the margin of the fabric in extendingthru the meshes thereof to retain the fabric against a stretchingVtension.

lt is found in practice that owing to the stiff and uneven or wavycondition of the edges of wire mesh fabric that the ordinary tenter clipin a tentering machine cannot be relied upon to engage the margin vofthis fabric for stretching the same and therefore 1n order to provide aclip which will act upon fabric of this character, I have-provided onehaving a body portion which is slotted to receive the margin of thefabric and so assist in straightening out some of the bends in its wiresas the same is drawn into the clip and I have provided in the clip oneor more fingers or members preferably a plurality each shaped at its endportion to independently enter the vopen meshes of the fabric and soretain the fabric whilereceiving the tensioning action, also Ipreferably so form these engaging members that they Will ride on themargin of the fabric and so be retained out of engaging position untilthis margin is withdrawn to a predetermined position at which time thesemembers are permitted to freely drop into the meshes in the fabric andengage the margin thereof to securely retain the fabric4 against thespreading tension. By employing a plurality of these members I insurethe engaging of one or more of them into the meshes of the fabric andthat the refusal of one or more to drop by coming in contact withportions of the wire or other reasons will not prevent the others fromfunctioning; and the following is a detailed description of the presentembodiment of my invention and showing one construction of clip by whichthese advantageous results may .be accom- With reference to the drawingsl0 designates the body ofthe clip which is carried on and secured to theusual chain link por- This body portion is provided with a longitudinalslot or guide l2 open at its front and sides to receive and guide themargin 13 of the wire fabric. The edges 14 of this slot are preferablyrounded as best illustrated in Figure G to smoothly guide the marginaledge of the fabric, vwhich is -morel or less wavy, thereinto.

This body member is herein shown as being ofha substantialmwidth andprovided with a plurality of spaced slots thru the upper wall 16 thereofand Vcorrespondinfr recesses 17 in the lower plate 18 thereof. Thislower plate is provided with holes 19 therethrough to receive the endsof the hook,

presently described" and also 'to permit fiakes of the metal to falltherethrough and so prevent clogging. -This body portion is alsoprovided with spacedpivot ears 2O through which a pivot pin 21 extends.

n that when the margin of the fabric'is `drawn outwardly from., underthe riding portion 23r of the blade, the notch 24 in this plate or othershape will permit the vblade to drop into the position best illustratedinl Figure 5 and socausethe portion 25 to enter the mesh and engagethemarginal wire 13 of the fabric and hold it against being withdrawnfrom the clip. f f p Each yof these blades is provided with a rearwardlyextending portion 26 tobe engaged by the usual part. notr shown of aten-'teringmachine to lift the blade at one end of the machine to permitthe entrance ofthe fabric into the -cl'ip andi-at t-he opposite end ofthe tentering machine to lift and disengage these hooks or lretainermembers from .the meshesv of the fabric 4after it has been operatedupon. 1 A

It Will'beobSe'rved -that byr my improved clip wherein'I employ avplurality of engaging memberswhich operate entirely in'- dependently ofeach other that the failure of lone or more to enter the meshes of thefabric would not prevent the other from functioning whichl mightnotbe-the case if all the members were connected to operate as a singleunit.

lMy improved tensioning clip is very 'simple vand `practical inconstruction, is

strong and durable and effective in its operation and by lits use wirefabric may be operated upon to receive thevstretching action of atentering machine.

v The foregoing description is directed solely towards .the constructionillustrated, but

Idesire it to be understood that I reserve the privilege of resorting toall .the mechanical changesto which thel device. is susceptible, theinvention being defined and limited only by the terms of the appendedclaims.
